How to use the tightening sleeve correctly can extend the life and avoid unnecessary opening value.
This should be done from the selection of procurement and use of the following things:
1. The torque value and the conveying thrust value are conveyed in the product description, which are the values used to tighten with the bolt-standard torque.
2. For items that use the maximum torque value of the bolt sitford according to the model, the torque value used is lower than the displayed value.
When greater conveying force or torque is required, it can be tightened with torque below the maximum torque of the bolt, but at this point the face pressure is also increasing, so the face pressure needs to be calculated first and the shaft and the center of the wheel material to match the face pressure can be selected.
3. In use, when the yield point of the material is exceeded, a sliding problem will occur, resulting in mechanical damage, so the face pressure must be confirmed.
4. Reference should be made to the yield point stress of all kinds of data recorded on the data page.
5. In order to ensure safety, it is recommended to use heat treatment materials such as quenching.
6. When there is an impact load, the safety rate of 3-5 times should be used for calculation.
7. The face pressure of the shaft or wheel center is not enough, so that the conveying torque is reduced, sliding problems occur, or the connection ring is attached to the shaft and cannot be pulled out, so the face pressure must be confirmed.
